Maxwell s Equations #8211; The four basic laws may be stated in integral form as given below: (i) Gauss s law for electricity, ∮E . dS = q/ε<sub>0</sub> (ii) Gauss s law for magnetism, ∮B . dS = 0 (iii) Faraday s law, ∮E . Dl = -dɸ<sub>B</sub>/dt (iv) Ampere s law, ∮B . dl = μ<sub>0</sub> I + ε<sub>0</sub> μ<sub>0</sub> dɸ<sub>E</sub>/dt
